. What was the Onondaga’s means of defense?

Bravo! The Onondaga was used for military exercises and to watch for Soviet ships that sailed along Canadian coasts during the Cold War. In 2009, it became the first submarine museum in Canada.

2
. What do we call the system for detecting obstacles using sound?

Sonar (SEW-NAR)

Absolutely! We’re referring to sonar. As a last resort, the submarine team emitted a sound signal in the water (active sonar) to identify obstacles and potential enemies.

3
. Where were the submarine orders given?

Control room (CON-TROLL-ROOM)

The orders were given in the control room. On board a submarine, rank and discipline are very important. Everyone has to work effectively together under the orders of the commander and seven officers.

4
. What do we call the place where the berths are located?

Main bunk room (MANE-BUNK-ROOM)

Well played! There’s not much room in a submarine. The crew sleeps on narrow cots located in the main bunk room.

5
. What do we call doors that prevent water from entering?

Watertight (WHAT-ERR-TIE-GHT)

Yes indeed! The doors are watertight. A submarine has four doors. If a submarine started sinking, endangering the crew’s lives, submariners had to put on a survival suit and leave the submarine through the emergency evacuation hatches.

6
. What means of propulsion were linked to the submarine’s engines?

Propellers (PRO-PAL-LAIRS)

Bravo! The propellers are connected to the engines. The Onondaga is 90 m long and weighs more than 1600 tonnes—the equivalent of 150 school buses! Two electric motors fired by two diesel engines were used to move this giant forward. Each engine is as strong as a locomotive!

Bravo! You did it!
